CLARENCE APPLEGATE, OF EVANSVILLE, INDIANA, ASSIGNOR OF SEVEN- EIGHTHS TO PETER EMRIOH, ABRAHAM EIOHEL, AND MCDONALD BROTHERS, OF SAME PLACE.

FEED-WATER HEATER.

SPECIFICATION forming part of Letters Patent No. 615,517, dated December 6, 1898.

Application filed May 24,1898. Serial No. 681,547. (No model.)

To aZZ whom it may concern.-

Be it known that I, CLARENCE APPLEGATE,

a citizen of the United States, residing at or jets of heated water are caused to sweep across the boiler in the direction of its length and to dislodge and carry away to the usual outlet to the attached mud-drum any sedimentary matter which has settled upon the fire-wall, thereby keeping the boiler and its tubes clean and reducing to a minimum the formation of incrustation and smudge and the consumption of fuel forheating the boiler.

My invention consists in combining with.

a boiler and its mud-drum the feed-water heater whose construction and arrangement I will hereinafter describe, and specifically point out in the claim.

In the drawing hereto annexed the figure represents a perspective view of ahorizontal boiler with its shell partly broken away to disclose the feed-water heater.

In carrying out my invention I may use the construction with any well-known type of locomotive or other boiler having horizontal tubes and superposed steam-space.

In the drawing the boiler A is shown detached from any furnace; but it will be understood that it will be so mounted and related to a furnace and its accessories that the water in the boiler will be heated by the products of combustion in the usual and wellknown manner. Beneath the boiler is a muddrum B of the usual character connecting with the boiler at its lowest point and being versely across the steam-space above the flues of the boiler are horizontal bars or supports 0, which extend from side to side of the boiler and are provided with short vertical bars D, upon which the feed-water coil E is supported. This coil has a terminal-or pipe E, which connects with the locomotive-tank or with any other suitable source of supply, and it may be used in connection with any of the valve-operating devices, injectors, and other accessories of a modern boiler. These are not shown, as they form no part of this invention. The pipe E enters the shell of the coiler from the top and is formed or connected with the coil E, which runs back and forth in the boiler and extends for a considerable distance along the steam-space.

As many bends or coils may be used as found desirable, and these are disposed transversely in a common plane and are designed to be seated upon or fitted to the vertical members D'of the support-bars C. By means of these short bars the individual members of the coil are spaced and prevented from warping, and each member is supported at the uppermost limits of the steam-space, where the heat is always the most intense, and the coil is clear above the water-line and the boilerfiues. The other terminal end of the coil is formed or connected with a vertical member or pipe G, which passes downwardly through the water and between the flues until it reaches a point proximate to the fire-wall of the boiler, when the lower end of the pipe is connected with a pipe H, which projects horizontally and extends along the fire-wall for a considerable distance, its discharge end point ing toward the outlet to the mud-drum and lying substantially in line with the smudge or sedimentary matter which deposits upon the fire-wall, whereby the jet of feed-water discharging from this horizontal portion of the pipe exerts its full power to dislodge and sweep away to the outlet to the mud-drum any accumulation of sedimentary matter, this action being continuous with the supply of feed-water to the boiler.

The construction herein shown and described is exceedingly simple and efiective,

and extensive experiments show that by-making the coil extend through a large portion of the steam-space and locating said coil close to the top of the boiler the water entering the feed-pipe is highly heated during its flow through the tortuous passage, and it is dis charged into the boiler in line with the sedimentary deposit, with the result that the boiler is kept clean and the interior of the boiler and the fines kept free from incrustation, and by preventing the formation of these coatings I am enabled to raise steam to a given pressure with a minimum consumption of fuel.

Having thus described my invention, What having its opposite end connected with a pipe'which extends downwardly-between the boiler-tubes to a point proximate to the lower wall of the boiler, a horizontal pipe connected with the lower end of the vertical pipe and extending for some distance along, close to and parallel with the lower wall of the boiler so as to discharge in the path of sedimentary deposit and remove the same simultaneously with the admission of feed-water, and means for supporting theindividual members of the coil consisting of bars passing transversely across the steam-space and below each end of the coil, and having vertically-projecting spacing-bars adapted to engage and support 1 claim as new, and desire to secure by Letters Patent, is-

An improved feed-water heater consisting of the combination with a boiler and its connected mud-drum, of a coiled pipe horizontally disposed in the upper limits of the steam-space of the boiler, and havinga feedwater-supply connection at one end, said pipe the separate cons 1n the steam-space.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- HGSSGS.
